Slip stitch patterns with hand transferred stitches, double bed

It is also possible to create solid color patterns on the purl side on a striped ground by at first transferring all stitches down to the ribber, then, in turn, using slip stitch selection on the top bed to choose only the stitches that will be manipulated on the main bed. A similar repeat worked on the single bed, may be found in the previous post on Slip stitch patterns with hand transferred stitches, single bed. And a relative, including a double bed version: Bowknot/ Butterfly stitch on the machine, and: A no longer “mystery pattern”.
When working over a striper backing, the color changer is generally in use, and changes happen in even numbers of rows. In my test swatches changes are made every two rows, and whether single or double bed, the color yarn creating the solid color shape needs to not knit while the alternate color is worked only in the background. The held stitches grow in length.
End needle selection is canceled in my samples. The extra needle selection prior to the next all knit row helps track the direction of the moves, stitches are moved three at a time, there are no cable crossingsThings do not always “work”, that is part of the process The next step for me was to explore cable crossings on elongated stitches working double-bed. A basic pattern on any programmable machine for playing with elongated stitches on one bed while knitting every stitch on the other is to program pairs of blank rows followed by solid punched or black pixel rows. The yellow line in this chart illustrates the row on which cabling might occur. Programming the width of the needle bed allows for only the stitches forming vertical columns in chosen locations to be put into work, allowing one to place groups that will involve crossings anywhere on the chosen pattern width. A base is knit in the ground color, which slips for 2 rows on the main bed, creating the elongated stitches that will be cabled. I had no problem with 2X2 cables,  but as in working on the single bed, for me, straightforward 3X3 crosses were not cooperative, even when I attempted to introduce extra knit stitches on the sides that were then dropped for added give on the last slipped row, taking me back to the drawing board. Cabling, returned to in a later post, with adjustments, making things work. Continuing with shapes on striped grounds, this is the result of a self-drawn pattern  The approach is different than in the blog post on Brother shadow lace, rib transfer carriage, where shapes were created in only one color, and the textured patterns by bringing needles in and out of work on the ribber. To create the striped ground in the above, color changes happen every 2 rows. The ribber knits every needle, every row. With the ribber on half-pitch, the transfers are all made from the main bed needle to the needle immediately below it and slightly to its left.
In the chart on the left, the green cells represent black pixels that will be programmed for patterning on the top bed, red cells, the stitches on the top bed that need to be transferred down to the ribber on the respective row.
Grey cell rows stand in for all blank ones in the final repeat.  This design is too wide for punchcard machines, but the fabric is possible there as well in different widths, isolated or all over. After casting on, all stitches are transferred to the ribber. Border, plain knit stripes can be added by simply having a larger number of needles in work on the ribber than the planned pattern width. With no needles selected in the pattern on the top bed, those ribber stitches will simply knit every row.
These fabrics are a little different than those with needles out of work on the main bed while using the slip stitch setting, in which case KC II on electronics, end needle selection needs to be turned off on all models. When all needles are in B position, depending on the pattern, KCI may be used. Simply using KCII eliminates any guesswork.
The first preselection row is toward the color changer with the knit carriage set to slip in both directions, only patterned area needles need to be in work. Non-selected needles, as usual, perform no function while those corresponding to where black pixels or punched holes occur will pick up loops on the top bed, initially creating eyelets, and then continue to form knit stitches until any of the corresponding stitches are transferred down to the ribber. The pattern yarn forms a short stitch in one direction, an elongated one in the other. A detailed close-up of stitch formations Plain striped rows in areas without the design continue to be knit in the slip stitch setting, or every needle in work on the top bed will pick up loops.
When hand manipulating stitches it pays to be mindful of maintaining all needles in the pattern in B position, not accidentally sliding them back to A.  In the past, I have attempted pile knitting on my machines. Studio machines produce the best fabric in the category, I have read Toyota performed as well. Books such as this are a good source for pile designs, including the card repeat used in my proofs of concept Punchcards, in theory, may be used as given and set to double length, while for use in electronics drawing the pattern single height and using the double-length setting is also an option. Starting sides and fixing errors have always been more confusing for me when using the double-length feature, I prefer to punch holes or program pixels as I intend to knit them. The isolated reduced repeat for use in the electronic is charted, with an initial one-pixel error in 2 consecutive rows, marked with red cells. In transcribing any design, it is worth checking repeats multiple times after eyeballs and brains have had a rest. This was my start:
The design process using Numbers before exporting the repeat to Gimp for reduction to B/W png: in this approach, the repeat is drawn double height to start with. The red cells represent stitches that will be transferred down to the ribber before knitting the next row in the pattern color from left to right.  The first test is of an isolated motif. The yellow arrow points to the pixel error, the cyan to the positions where some needles in the full repeat were “accidentally” placed in A position, not B, resulting in pattern stitches not being formed.  Another review of the original card, a final adjustment in the repeat: Tiled view, committing to the result, the larger test swatch Two other options for charting the fabric in numbers: A. draw the repeat as given
B. starting cell size used was 20X20, change the height to 40
C. mark corner blank cells and screengrab for Gimp import
D. the repeat processed in Gimp matches the first version
Any simple Fair Isle repeat may also be used. The numbering in the charts matches what is normally seen on the left edge of the tables
A. the FI repeat, 8 rows high
B. a table slightly longer than double the repeat height, hide even-numbered rows
C. copy and paste the FI design on the table with hidden rows
D. unhide rows, isolate the repeat, adjust cell height, and continue to process as described above 

The original punchcard design may be used in a different manner if the goal is a single color fabric. The design may be copied as is, then filling in the blank lines with the same holes or pixels as in the row directly below it. Here, in addition, the repeat is altered to accommodate a half drop repeat on the right with a few pixels changed. My initial proof of concept is 32 stitches wide, narrower than the full repeat The rows need to be scanned before every pass, as transfers to the ribber are not symmetrical due to the shapeshift on the right of the design. The world of possibilities grows even further for single color shadow lace, when, examining the same design, one recognizes that the pile knit card, with the blank rows filled in in pattern, is the same as the fair isle version of the repeat, rendered double long Some authors have suggested plaiting as an alternative to creating shapes with true brioche, which can be complex.  To my mind, plaiting falls in the beauty being in the eye of the beholder category, I prefer far crisper color distinction in my knits. This sample from the previous shadow lace post uses thick and thin yarns  Using the image adapted from the studio pile card once more, I tested using 2 yarns of similar weight, the adjusted test repeat: its accompanying test swatch

I have long been interested in pleated knits, both single and double-bed. Working single color or with plaiting makes the repeats easier for DIY designing. Seeking proof of concept for possible “origami” pleating: on the left, yellow marks the spots for transfers to the top bed, which will create folds out toward the knit side. For folds toward the purl side, stitches are manipulated on the ribber, with the final design repeat shown on the right. The ribber carriage is set to knit throughout. The needle from which the stitch is transferred to the main bed is moved completely out of work. After the transfer, the main bed needle accepting it is returned to the D position.
The knit carriage is set to slip in both directions, end needle selection is canceled.  Subsequently,  non-selected needles, 1 in the photo, serve as guides for transfers to the ribber, made every two rows. The needles emptied from the transfers need to be maintained in the work, B, position. The selected needles, 2 in the photo, will pick up loops automatically, creating eyelets as seen in previous swatches. The swatch would have benefited from tighter tension or thicker yarn, the folding effect is greater than reflected in the photo. Initially, those pairs of center stitches were not transferred up to the main bed, showing the absence of that fold when that action is omitted. Any of these patterns benefit from deliberate planning of the placement of the pattern on the main bed, not done in this instance.   Transitioning to smaller repeats, tiling will help avoid patterning “errors” as seen here where the full diamond shapes reverse  Graph paper or spreadsheet planning will help avoid misses in necessary transfers in areas where all needles have been selected the file for multiple repeats after color reverse the test knit as using transfers as described above and here the empty needles creating the eyelets were filled by picking up the purl bar from the stitch below on the ribber. A lot of work for a change that is not significant in the structure of the fabric.  In my last test on eliminating holes and how that affects the degree of the folds, transfers to fill in newly selected needles on the top bed were made from below the adjacent needle on the top bed, B, as opposed to immediately below on the ribber, A If patterning is used to track transfers, needle selection on the top bed needs to be maintained throughout, the result of this process is not interesting enough and just too fiddly and time-consuming for me to be interested in exploring it further There is an interesting scale and depth of fold comparison between this version and the first using the repeat, achieved by tightening the tension as much as possible, and possibly by reducing the size of the eyelets.

Exploring manipulations with more than one color patterning on the main bed: there is a type of DBJ that relies on knitting the same color for 2 rows that is inherently different from the KRC built-in separation that is the default in the Japanese model machines. It causes elongation in the design, while the KRC version minimizes it. The differences and methods of the corresponding color separations have been discussed in other posts. Stitch manipulations may occur when working DBJ as well. Simple designs make the best start for beginning to explore the topic An easy variation is to plan full repeat segments mixed with a striped ground worked only on the ribber Take care if copying and pasting single columns to alter a repeat width that the whole column is indeed copied and that if using the pencil tool flood fill is not used unintentionally. The original intent was also to correct the elongated slip stitch segments on the edge of the programmed vertical designs marked in blue, but the paste with errors in red accomplished creating the same issue The design is programmed for DBJ. Because of the color separation used, the first preselection row is from right to left. Before knitting the first pattern row, all 10 non-patterning needles on the main bed were transferred down to the ribber. The first segments were knit using striper backing, with the ribber knitting every stitch, every row, in both colors. When a slip stitch is used with needles out of work on the main bed, end needle selection should be canceled. In A it was not. The result is that end needles alongside the out-of-work column knit with each color in each row. In B, end needle selection was canceled, and one can now see the elongated slipped stitches that result from areas that should have been marked with the contrasting color As long as the number of stitches on the ribber is even, lili buttons may be used, affecting the scale of the pattern in both height and width. In A, they were used with the ribber set to slip in both directions, in B, set to tuck in both directions. C marks the return to the N/N setting, with needle transfers to mark a possible pleat. The initial pleat idea charted out for single stitch folds, stitches transferred to ribber in the R columns, to the top bed in the T columns The result is a fairly soft pleat, the choice below was to retain end needle selection.  Various ribbed pleat configurations are explored in Pleats: ribbed, folding fabrics. This repeat may not be the best to use for a variety of reasons, but experimenting while using the same design and yarns can be useful in understanding stitch formations. Theoretically, the alternating direction of folds should create sharp or knife pleats. folds up asPaired transfers in the planning stages: because the repeat is small and has a single center pivot point, it is rendered once more, adding columns Here the transfers planned to opposite beds are marked on a 48 stitch repeat with red cells.
The resulting fabric relaxed on the left, lightly steamed on the right Note: the color positions in the design have been reversed from those in the first swatch. If “floats” are noted at any time in the spaces where needles are out of work on the ribber, look for dropped stitches.

Vertical bands of color,  even in patterns may be transferred to and from beds to achieve a sort of intarsia effect. One option is to work with vertical bands of fixed color, using the KRC built-in separation. When shifting gears it is useful to remember the starting side for the preselection of the first row of patterns. With many of the previous patterns, designed for color changes every 2 rows, starting side was on the right, toward the color changer. With KRC in use, the first preselection row is away from the color changer on the left, moving toward the right. With either method, starting on the wrong side will knit stripes as opposed to planned patterns.  Needles in locations where only the backing is to be shown are transferred down to the ribber. Leaving the eyelets, they were transferred back up to the main bed when brought into work to reverse or change the shape. Addition and subtraction of stitches take place before the next pass with the alternate color. Here movement is random, to get some sense of the effect, it could be made deliberate by following a chart or color separating and automating the pattern, with its starting side on the right.  This sample is from a much earlier post. Transfers could be made less frequently to change the angles in the resulting shapes, always onto the same color What of having shapes appearing in each of the 2 colors on a striped ground? Eliminating some of the guesswork I used the repeat from a previous single-bed blog post on block slip stitch color separations The repeat, 32X44The resulting sample, the yarn is thin, might have benefited from tighter tension and more contrast.  These fabrics and related shadow lace ones fall in the category of double bed embossed patterns, many more variations are possible, and deserving of their own post.

Knit weaving 1

In knit weaving, the knit carriage is threaded with the main yarn as usual. The choice of pattern is determined by needle selection. The most basic technique involves pulling the desired weaving needles forward manually or by using needle pushers which are available in a range of selection options. Automatic needle selection makes the process faster, consistent, and capable of more variations.
The weaving yarn, according to instructions in manuals, may be threaded through the tension mast and guided through the weaving yarn guide. Feeding thicker yarn smoothly through the standard mast may become problematic. Moving yarn from the groove on one side to that on the other is cumbersome. The punchcard machine manual for the 860 machines has some clear illustrations and directions  From the 260 manual: The “yarn guide” is that mysterious notch in each arm of the sinker plate. In the Studio accessory, the AW1 weaving arm, the yarn is also fed through the yarn mast, and moved physically from side to side after each pass of the carriage. Start the piece with waste yarn and some evenly distributed weight based on fabric width. Make sure the weaving brushes are activated. In Brother standard, their position is changed using the corresponding lever, in the bulky 260 the L and R wheel brushes need to be placed in their corresponding slots.  A good repeat, to begin with, is one that selects every other needle, every other row. The card is a standard factory issue with punchcard machines. In general, the knitting yarn is thinner than the weaving one. The tension needs to be adjusted to accommodate the surface yarn, not the background one. The tighter the tension the firmer and narrower the weave. It is also possible to create soft knits with a lot of drape ie by using sewing thread for the ground and fine mohair for the weft, there is a huge range for exploration.
The “weft” precedes the base knitting yarn which knits the stitch. It is laid over the top loop of the old stitch on a needle selected by a hole in the card and goes underneath the top loop of a previous stitch on a needle not selected by a blank on the card. When card 1, above, is in use, the weaving yarn is caught in a series of two loops, one above, and one below forming a honeycomb effect.  The structure is typically illustrated in these ways in Japanese reference books and magazines in particular. Early Brother punchcard volumes have illustrations of the over_under structures and in-between floats along with providing the pattern repeats. Setting things up:  the weaving yarn is in front of the machine, fed from the floor. The short end goes to the carriage side, the long end is away from it. It is laid in front of the gatepegs, atop selected needles. A clothespin can provide enough weight on the short end to keep it from riding up and having to be managed with one’s hand. “Weaving” can begin from either side, here it starts on the left. Knitting in 2-row sequences will return the yarn ends to the starting position. Locking the card, as with any other pattern, will repeat the same needle selection, creating vertical repeats that resemble twill weaving on a loom.
a: card set to advance normally, b: card locked a: because stitches are actually knitting every other row, slipping while the needles on each side of them knit, they will alternately be a bit elongated; b: same needles knit every row, so their appearance is consistent. Depending on the difference in yarn thickness, the knit stitches in the ground become forced apart with what can be significant “bleed-through” on the reverse of the weaving to make that a really interesting fabric feature as well.
Some weaving patterns with variable floats will produce better edges if the end needles are brought out to E in every row if not selected to that position by the reader.
If a hairy or fuzzy yarn such as mohair is used the fabric may start to bunch up, it may be necessary to reach up from behind the knitting and gently pull to release the little hairs from the gate pegs.
Most punchcards designed for weaving aim for short floats formed by unpunched areas, longer ones on occasion are planned for added manipulation.
Moving the yarn from the groove on one side to that on the other is cumbersome. Another way of working: the main yarn is threaded as usual and the weaving yarn sits on the floor. The method is often referred to as intarsia weaving. The shapes may be created using various punchcard designs ie diamonds, squares, etc, free-forming, or even through following planned drawings on knitleader mylar garment shapes.
The knitter guides the yarn. If the yarn is held too loosely it may jump off the knitting while weaving and thus create long loops. It should be guided and held just enough to slip through the hand as the carriage is passed.
Preselect for the first row of knitting. Lay the weaving yarn across selected needles in the direction in which the carriage will be moving.
If using yarns of different yarn weights within the piece, multiple strands of the thinner yarn may be used together, but test how the strands feed and if plying might lead to problems. Using wrapping methods on some rows or even creating floats and hooking them up periodically can produce added interest.
If using more than one yarn per row, the approach is similar to intarsia. In true intarsia, every needle is in use. These illustrations are from an intarsia carriage manual;  positioning the yarns for a first row from right to left, the “wraps” needed in each direction In knit weaving, assuming the first pattern row is preselected from left to right, with COR, the short end of the yarn of the carriage side, bring the first weaving yarn up from the floor, and lay it to the left across the selected needles, bringing it down between the last selected needle for A, and the first selected needle for B. In one method, bring the long end of the second yarn, B, up on the right side of the needle over which A just crossed, and lay it over the remaining selected needles and down to the floor. Small clothespins may be used to hold the short ends in place. When all the yarns have been laid in, grasp the ends loosely, pass the carriage to the left, and the first woven row will have been completed. The carriage will now be on the left, COL. For the next row begin on the right, bring A up and between the two needles directly above it, take it over selected needles to the end of selected needles, and down to the floor. Then take yarn B and bring it up around the left-hand needle, over and to between the two needles that served as the starting position for A. The yarns do not overlap the same needle going to the right, but they do to the left.
The more traditional intarsia crossings may also be used, with the new yarn passing under and over the old between needles, as seen here with the next row to be knit from left to right. a: crossings made using the traditional intarsia method, b: wrapping over the adjacent needle moving from left to right, c: no crossing at all also revealing single knit stitches between weaving yarns. In some spots, my weaving yarn split and got knit along with the ground yarn. To create isolated shapes: lay the yarn in any chosen area Shaping may happen in a straight vertical, a, there may be a slight separation along that edge. Increases are possible on both sides at the same time, and are best done by adding single new selected needles to the pattern, b. Moving further out crossing over more weaving needles will cause floats, as seen in c and d. The woven segment forces the knit stitches apart, so the stocking stitch on either side of the shapes, e, appears to be formed  by smaller stitches, and pulls in toward the shape 
The ground yarn and color may be changed for added striping and color interest. Sharp angles are created by crossing over two weaving needles, and more gradual ones by crossing over more needles. Blank areas of ground may be left as well.
The intarsia approach may also be used with other cards designed for all-over patterning.

Using far thicker yarns may be made manageable when changing the card repeat or using weaving repeats with 12-stitch wide repeats, working on specific needles on a punchcard machine, or simply programmed twice as wide on electronic ones. The expanded version of every other needle set up for the punchcard models.  Sometimes plain knit rows need to be added between lines of weaving to help manage thicker yarns in any configuration or to add color interest and width changes to the piece.
Woven rows may be used to create folds in pleats.

Other weaving techniques include the pulling-up method, as a stand-alone or combined with lace patterning: from a Brother punchcard volume Three more hooking-up variations, including latching graduated-size floats 
A later experiment combining weaving with tuck patterning Hand techniques: e-wrap rows may also be incorporated with any of the above or used alone, sketches of some varieties may be used around every needle or every other depending on the thickness of the yarn: a sketch eons ago  Commercial warp knit structures are often represented as in this illustration. On domestic knitting machine models, a knit ground is needed to anchor the moving loops, which in turn are added on as a hand technique, referred to as vertical weaving, sometimes simply as embroidery.
Japanese instructions that came with the purchase of the standard garter bar had schematics for a variety of surface treatments. The accessory came with foam-backed strips intended to be clipped onto the width of the garter bar segment being used, useful in maintaining even spacing between yarn threads when working on wide areas of vertical weaving, as well as providing helpful weight. Any weight used to help handle the long ends of the weaving yarn on any number of threads will need to be moved down periodically.    More wrap ideas Variations can happen by changing the spacing between wrapped stitches, the number of rows between the moves, spacing threads apart, and using yarns in different thicknesses and colors.
In terms of tools to hold the weaving yarns, in addition to the garter bar, multiple transfer tools may be used, even bobbins. That said, the most efficient way is to have a guide suitable for the overall fabric, especially when creating wider pieces with spaced weaving repeats. It is possible to create cardboard guides with holes based on gauge, whether on the standard or the bulky and with 3D printing nowadays a whole other world for custom tools is open. Matching the gauge with guides has some leeway, but the closer the match, the faster and easier the process. When using thicker yarns for the warp knit, spacing in both stitches and rows becomes a necessity.
A half-hearted attempt at a template. Markings were generated to be point/mm specific. If working in narrow panels, individual segments may be more effective to manage if a bit slower to use than a wider tool.
This is the wrong way to feed the yarn, as the row gets knit woven in, the yarn will be locked in place and cannot be advanced to proceed up the knit The way to have continuously available yarn Adding a second set of holes for the yarn stabilize the short yarn ends and maintain even spacing throughout, some tape could be used in addition to secure the ends on wider widths of vertical weave A spreadsheet or graph paper may be used to plan the configuration of the weaves including double wraps, this was executed using Numbers, individual bobbins might be a practical consideration In my own experience most hand techniques and single bed textures are far easier to execute with the ribber removed. It is easier to view progress, move up weights, and correct mistakes. That said, my machines are all set up with the ribber brackets, not flat, I feel it helps slide the knit down toward the gate pegs, and in my opinion that makes textures and even lace easier to produce. I have ribber covers, they can be improvised if needed with paper or cloth, never use them since I see no reason for moving the knit on the top bed in front of the ribber. If the ribber is removed, it is worth checking its balance once more prior to returning to any rib knit. Ultimately this sort of thing is about personal preference, no steps are ever universally applicable and correct.

Tufting may be created with the help of a sewing machine.

“Weaving” foreign objects can be achieved by picking up loops from other knits, woven, trims, crochet chains, etc. Beads may be threaded onto weaving yarn as well.

 

Knit weaving 2: swatches, experiments

Many of these swatches are part of my stash from my teaching days. They were usually not intended for finished pieces, merely to illustrate a range of possible results with the techniques, often produced during my demonstrations. The colors were chosen to stand apart in the shared yarn stash in the studio, intended only for my personal use and for easier visibility during demos. The latter were being videotaped from some height and projected onto a large screen during classes for added visibility. At times enrollment was between 15 and 20 students per session.
Eyelets indicate tension # used for ground yarns. It is best to avoid dots between whole numbers. If swatches are too small to reflect the tension used, knots can be placed on yarn ends at the start of each experiment. The ends themselves may need to be doubled to make knots palpable.

Weaving yarns may be laid in between the beds with the ribber in use. This is the option for “weaving” on the Passap. 1: shows the rib needle configuration, 2: racking is added, 3: floats are teased out. In the latter, a sewing machine could always be used to anchor added float arrangements. In this swatch, a waffle weave effect of sorts was intended between EON rib columns. The horizontal pairs of treads are an easy guide for feeding the yarn across rows with the work off the machine. Here the chenille was “woven in” off the machine using a tapestry needle, double-strand at the top 2 rows, single below them. Beads can also be threaded and laid in one at a time between the rib columns, Any fabric with eyelets may be used as a ground for inserting fabric strips, very thick yarns, even hard objects such as rods or twigs. A quick grab of random studio bits resulted in these: torn fabric has frayed edges that can be used to create secondary patterns depending on the fabric, and the way the strips behave depends on the width of the cut. A bodkin is useful in the threading process. Bodkins measure about 3 inches, and cost about $3 in US sewing supply stores a narrower strip of the same fabric began to permanently twist using thick yarns  Plastic bag strips “woven” on a Passap, “floats” were cut after finishing the piece used in a wearable made during my student days for a “recycling” art day.

Slip stitch patterns with hand transferred stitches, single bed

This post originally included samples worked using needles on the ribber as well, now in another in progress post: Slip stitch patterns with hand transferred stitches, double bed
An earlier post with a range of single-color experiments: A hand-knit consult to machine knit slip stitch
The inspiration source for the topic here was found on Pinterest Adapting the motif for machine knitting, visualizing the actions needed. The repeat is suitable for punchcard machines as well. The first preselection row is toward the color changer, end needle selection is on. Cable crossings, 1 front, 3 back, are made every 4 rows except where the color reverses at the midpoint, where 4 all knit rows are preselected and occur. The fourth, extra non selected needle, X, is removed on a tool and held in front of the work. The three adjacent stitches are then also removed on a tool, moved to fill in the now empty needle to the left in the bottom segment of the repeat, to the right in the top half. The remaining held stitch is then transferred onto the newly empty needle. All stitches in the transfer group are brought to D, the remaining needles should have been preselected. If any have been disturbed, line them up as well so all the needles will knit with the carriage set to slip. The color is changed, and the row with the completed transfers becomes the first all knit row in the next color pair or rows. 
The repeat as programmed into my 930
Working on a single bed is for me, more user-friendly than double bed. I like to program the width of my repeats when possible, they can then be treated as single motifs, the default in the 930 with downloads using img2track, and I do not have to rely on notes, memory, or position programming to place the work predictably on the needle bed. My full repeatThe knit carriage was set to KC I and to slip in both directions, the same design and execution methods were used as for the first swatch. The yarn is 2/18 wool, the tension was set at 4.., the slipped and crossed stitches pull the fabric in both width and height, the swatch was steamed and pressed to flatten it. Small eyelets occur along the edges where the single stitches were moved to one side or the other across three needle positions. It was not possible to produce a 3X3 crossing at the center of the shapes. Over time I have encountered illustrations of unraveled knit or slipped stitches being brought out to the purl side, creating thread patterns on the knit surface, and changing the color structure on the purl. This illustrates a slip stitch being created via a hand technique Here the dropped stitch is hooked up on the purl side  Using the automated slip stitch setting simplifies the technique. The method often described to deal with moving the elongated slipped stitches is illustrated below. Using a latch tool inserted behind the slip floats, remove a single slipped stitch at a time, passing it under the slip stitch floats, and rehanging it in its original needle position.  In testing techniques, a simple design that is recognizable with the preselection of needles makes it easier to track progress and accuracy. Though these patterns may be executed in a single color, working in contrasting, bright yarn colors is helpful in isolating stitch formations and understanding their structures. More than one stitch may be moved at any one time. I found when using more than 2 rows of slip the ground fabric began to look gathered and distorted, so my tests are knit using 2X2 pixel blocks.
To move the slipped stitches, slide a multiple eye tool under the slip stitch floats that are to be moved to the front of the knit, holding the tool parallel to the knit bed, lift floats up and onto the non selected needles,   pull tool forward, so stitches and floats move behind the latches push tool back toward the needle bed lift the slipped stitches and floats together onto the tool insert a latch tool from behind between the prongs of the multiple eye tool,  lift the floats over the eyes of the tool, placing them behind it and the slipped stitches, being careful not to hook them up onto gatepegs,
now lift the original slipped stitches back onto their previous place on the needle bed, they will be part of the first all knit row in the contrasting color;  bring the needles with the restored stitched out to E, thus making certain they will knit as the carriage makes its next pass The pattern is charted below in development, color changes were planned every 2 rows. The third blank row in each slip stitch location marks the spot for the above manipulations to take place, noted in the chart with grey cells marked with pink dots. After the initial preselection row toward the color changer, only for the first all knit pattern row, push non-selected needles out to hold, E, to ensure all stitches will knit in the ground color. Subsequently, the first design row is part of the continuing repeat. The next color change will begin to form the floats. The sequence at the bottom of the swatch is off because I had a change of heart about which color I wanted to form the solid color shapes To my surprise, the process became oddly meditative, and I moved onto a different motif built with 2X2 pixel blocks. As seen with mazes and mosaics, a design intended for standard fair isle, tuck, or slip, with color changes every 2 rows, will produce an altered final shape,  Combining hand techniques: the starting chart begins to address the movement of stitches. On the left, the placement of crossed colors is shown, but technically the design produced is different. On the rows marked with X and red cells, cable crossings are made. All stitches in that row are then pushed out to E, the color is changed and the result is that row and the preselected next one are going to knit on every stitch, those rows are highlighted with red cells on the right as well. Black cells reflect punched holes or repeat for a 24 stitch brick repeatTwo types of crossings were used in the swatch, one moving the elongated slipped stitches on the knit side of the work, the simpler process,  the other involves moving the slipped stitches to the purl side of the work which the purl side after slipping the slip stitch floats behind them in the first steps, followed by performing all crossings to the purl side, then bringing all the needles out to E, changing the color, and continuing in the pattern. The blank line indicates the crossing row, the numbers the rows actually knit. The resulting knit proof of concept: the fabric has a 3D effect. My red yarn is an acrylic chosen simply for thickness and contrast that flattened with a bit of steam. The white yarn travels in two opposite directions for the crossings, creating eyelets in the center of each pair of moves. The slip stitch floats brought to the knit side in the top half nearly disappear on the knit side. Both surfaces are “bumpy” A design with each color being crossed: the attempted visualization and repeat. The repeat appears to use slip-stitch in a vertical column, not ever possible in standard knitting. The explanation is that on those blank rows, crossings are made prior to knitting the next row. The chart on the left reflects the needle placement of each color after the crossings.  All pattern needles are then brought out to E, maintaining the needle selection. Slipped stitches will have been replaced by knit ones in the alternate color.
When ready for cabling, there will be 3 floats in one color, and a fourth, single one, in the other.
For the first row of knitting, there will be no preselection. Bring all those needles out to E with color 1, then continue as described.
My first test had 2 more rows in each pattern segment, I found the stitches persistently wanting to jump off the needles due to the amount of texture. The charted repeat Transferring the slip stitch floats to the knit side was fiddly, I actually prefer the texture created by moving the elongated loops on the knit side. All cabled fabrics narrow considerably. My swatch is 24 stitches wide, knit at tension 9, 14 transfer repeats measure a whole 2.25 inches in width, 4.25 in length. The white yarn is a 2/8 wool, the red a 2/11.5 acrylic.
The very first preselection row and those blank rows in a card or in pixels will only select the first and last needle if the cam button is set to KC one, signaling action needs to be taken the needle selection is fixed, so it easy to ID and restore after transfers are made. A couple more ways to transfer those slip stitch floats to the front of the fabric: floats can be lifted on top of the needles that formed them and behind the stitches on them, a fine knitting needle or tool can be inserted through the stitches across the row, a few, or a pair at a time, being careful not to twist the stitches. In turn, the stitches can then be dropped off the main bed, held on the needle or tool, and be replaced carefully on the needles in question across the row. Crossings are then made, the proper needle set up is manually chosen for the next carriage pass, and the process starts over again. Folks who like lifelines could thread a ravel cord threaded through a needle and use them to remove the same stitches off the bed instead of the knitting needle.   

Returning to cabling with crossings showing only on the knit side, attempting wider cables: several issues need to be worked out. The more frequently one color is slipped, the more rows the alternate color will knit, which will lead to distortion of the fabric in the striped areas. The greater the number of stitches crossed, the harder the cable is to achieve, so my tests use 2X2 cables. Dark colors are harder to see both when moving stitches, and often in the final fabric. Spacing between the cabled columns and whether or not to place them or all knit rows on the edges is another choice that needs to be made. The charted repeats are for the red cable with the second spacing, illustrating options for cabling on row 7 or row 11, pulling needles out to E after making the transfers before knitting the last row of the design. Pairs of slipped and all knit rows are added to lengthen the distance between cables and to reduce some of the extra lengths in all striped areas This idea may work in a border or a trim as well. I did not test bringing the slipped stitches to the purl side. The chart shows adjustments in the placement of the repeat to make tracking crossings easier The actions takenOne more to try If the goal is to add checks along with solid color cables, the best way to achieve the fabric is to use the fair isle setting. There will be 2 sets of floats formed with each carriage pass. A blank segment may be added at the stitch crossing location as in previous repeats, with those needles brought out to E before the next row is knit, remembering that proper needle preselection needs to be maintained throughout Another approach is to bring elongated stitches created manually up on the purl side. The resulting fabric will be more gathered on the knit side, with no formation of slip stitch floats, it is referred to as ruching, and may serve as a compromise when color changes are made over 2 rows of contrast

 

Pile_carpet stitch knitting on Passap and Brother KMs 3

Studio and Toyota machines could produce this type of stitch easily. Many efforts have been made over the years to produce the same fabric on Passap and Brother.

I was asked via a blog comment in my previous post #1 on this topic about creating a single color all-over pile on the Passap machine and have added these instructions
Executed with the lights off:
Cast on and begin with all stitches transferred to the back bed.
The back lock is set to EX, the front to CX, pushers are not needed
Knit two rows using those settings, and use a stitch ditcher to drop loops formed on the front bed.
One color carpet stitch, if programming technique #256, ignore console instructions
1. cast on so that all stitches are on the back bed
2. knit a few rows in stocking stitch testing for the tightest tension at which your yarn will knit, and experiment with the front lock tension to produce as large a loop as possible that will also drop off properly.  Begin knitting your test with locks on the right side: 
3. bring the back bed pushers to the in 1X1 arrangement, and set the back lock to FX with the left arrow key, not BX. Do not use the AX setting, it will tuck in both directions. All needles will tuck moving from right to left, and knit on their return to the right
3. with the front lock set to LX, it will knit on all needles when moving to the left creating loops on the front bed, while the back lock does the same, slips all needles moving on the front bed when moving back to the right.
When the locks reach the left side there will be loops on every needle on both beds. As they move from left to right, the needles on the back bed will knit, securing the loops there and anchoring the ones on the front bed while the front bed is slipped
4. with locks again on the right side, use stitch ditcher or another tool to drop off loops on the front bed, returning needles to proper work position, follow with a pass using a single eye tool to push loops between the beds, checking that none are left in the needle hooks
*make 2 more passes with locks from and returning to the right, drop off loops**, and continue from * to **
The difference in the size of the long stitches between loop rows in the photo was eliminated by tightening the tension on the back lock,  it is evident that they are anchored more evenly in those segments as well. As with any fabric, the larger the intended piece, the more likely some further adjustments may have to be made. Alternative settings for one color pile: Tech 256, back lock FX and both arrow keys, pushers one up, one down, front bed to LX, drop stitches every 2 rows.
For 2 color work, Tech 184, same settings.
For a similar effect on Brother machines, begin with all stitches in work on the ribber, with the settings: opposite tuck buttons, the main bed knits to left, ribber knits to right anchoring loops formed on the previous row the loops, formed on every needle on both beds with the move to the left anchored in place on the ribber needles as the only the ribber knits as it returns to the right while the carriage is on the right, drop all stitches on the main bed,   making certain no loops are stuck on gate pegs on the main bed, repeat the process throughout the piece. Occasionally skipped needles and their missing loops may not be noticeable, any loops hung up on gate pegs will be visibly longer. Tension needs to be “just right”. My first efforts, shown sideways Knitting was smoother with a change in yarn. An extra needle on each side of the knit on the ribber is brought out to hold manually to ensure their stitches knit with every pass of the ribber carriage. I prefer the all-over pile with its loops formed on the top bed. There were nearly no incidences of loops catching on gate pegs on the main bed. One of the drawbacks is that the main bed needles need to be dropped and brought back to the B position manually, bald spots will result where any needles are not returned to the proper work position, so they will not pick up loops.

The traditional hack for other than Studio or Toyota kms involved this process:
to knit, bring up the first and last needle to the hold position on the ribber to ensure they knit when both carriages are on the right and the ribber will tuck on every needle as the carriages move to the left. The carriage settings: Loops are formed on the main bed as it knits from the right to the left, and slips on its return to the right. The ribber tucks on every needle moving to the left and knits on every needle returning to the right, anchoring the main bed loops. After the carriages reach the right side, loops on the main bed are dropped, and the process is repeated.
The results are dramatically different. If considering patterning on the main bed with the addition of a second color or creating isolated motifs whether on a single color or striped background, anchoring loops by tucking on every needle is no longer possible, making reverting to EON needle selection on ribber a necessity. Loops formed where no stitches are knit on the main bed would only sit in the hooks on the ribber and create a mess. Hence the “hack” where lili buttons and tuck stitch in both directions so that loops are knit off on the next pass, and with 4 rows knit before dropping stitches so that the maximum pressure is put on those loops to hold them in place. This requires the tightest possible tension on the ribber, and by default, the EON tuck will want to spread the fabric further apart. I have found this version a failure in producing a stable fabric with a satisfying pile formation. Returning to the pursuit of pile loops in pattern on Brother: my first effort with a simple, linear shape produced separation aside the loops akin to that seen in isolated FI motifs, both when using the ribber or the main bed to create the loops. Here a simple checkerboard was hand-selected, there was separation along the vertical edge like that seen in isolation motifs and this is likely my last try at the single pile in a pattern using every other needle tuck on the ribber with the release of stitches every 4 rows. I actually like the elongated stitches in the ground but found the stitches planned for loops simply did not release easily or at all,  using thinner, smooth yarn resulted in breakage, while adding elastic obliterated loops, and wooly nylon simply broke regularly. It would appear if pile knitting on Japanese machines is the goal, by all means, add a studio KM to your stash ;-).

Unconventional uses for punchcards 3: lace in rib

Lace patterns for drop stitch: cast on as preferred, transfer MB stitches to ribber, where all stitches will be knit on every row. The main bed will be knitting the stitches that will be dropped (lace carriage will not be used), cancel end needle selection, program your repeat, push in both part buttons. As the carriage moves across the bed selected “lace” pattern needles will knit, the non-selected will be skipped.
Continue to knit until no needles are selected. At that point disconnect the main bed and ribber carriages, change the setting on the main bed to knit, remove the yarn from the feeder, bring the knit carriage alone across for 2 rows, and stitches will be dropped. After the disconnected carriage is returned to the opposite side, rethread, and connect again to the ribber carriages, set the knit carriage to slip and it once again will knit selected needles. Repeat the process for the length of the swatch. If on an electronic machine with 2 carriages: the number of rows is usually an even number, so an additional knit carriage with no yarn could be positioned on the opposite side to the one selecting pattern, set to do plain knitting, holding no yarn, and it will drop the stitches on “plain knit rows” on lace card without requiring the other additional steps and cam button changes.

Transfer lace on the top bed: the question periodically comes up with regards to the possibility of using the lace carriage when knitting every needle rib fabric. The lace carriage does not operate with the ribber bed in use in the standard up position, there is not enough clearance between the beds for it to travel from one side to the other across the needle bed. It is possible to drop the ribber down one click, opening up the space between the beds, supposedly to allow for the use of thicker yarns.

My machine is old enough for the ribber to be bowed in the center, increasing the space between the beds there. Trying to use that position for every needle rib in my desired yarn I got yarn breakage in the center of the bed, some skipped stitches, and the sides of the needle bed were still up too high for the LC to have a clear passage. The problem appeared to be due to its brushes hitting the gate pegs. With the brushes removed, but with some grinding against those same gate pegs the LC was able to move along the top bed. At least on my machine, I am giving up on the idea of using it, even if only to preselect needles, let alone make transfers.
This page is from the Ribber techniques book. The fact that transfers are broken up with blocks where there are no transfers, including some with stitches transferred to the opposite bed, makes it easier to track transfers than if using all over designs. Standard pronged tools are sufficient to move the single stitches or groups of three. 

It is possible to transfer larger groups of needles on the main bed to create lace patterns, done of necessity in two-color brioche, but here I am seeking to modify lace punchcards so that the fabric based on them may be created successfully with as few errors and dropped stitches as possible.
My first attempt was made using a second knit carriage set to slip in both directions to preselect needles for transfers,  using a small lace repeat to test the idea. The advantage of this method is that the original lace repeat does not need to be altered in any way. The disadvantage, aside from requiring a second carriage to use, is that the width of the piece on the machine is limited.  The ribber carriage is in use and needs to remain at least in part on the machine bed on the far right, limiting the number of needles for possible use on the right side of 0 to about 20. The same work could be done using only one knit carriage as well, but that would require changing the cam buttons from slip in both directions to knit and back to slip at the appropriate points, one of the methods that make it possible to knit lace on the 260 bulky machines

The repeat used is for this swatch is from StitchWorld, and is knit using the second knit carriage for needle preselection.  Because each block contains lace transfers in only one direction, the fabric, even though it is a rib, reflects that in the biasing first in one direction, then in the opposite.

It helps to be clear as to whether one is producing lace repeat for use in a punchcard or an electronic model which in turn will require mirroring, such as when using Ayab or when using slip stitch selection with the knit carriage in combination with lace carriage selections to create shaped lace edgings. Testing on a small swatch will help determine whether mirroring is required for any specific design. Electronic machines usually produce the design as seen on the knit side, punchcard machines as they would be seen on the purl, thus making mirroring a requirement depending on the source for the design.
I usually begin by modifying my chosen repeat in a spreadsheet. On the left, the pairs of blank rows in the original repeat are temporarily colored in grey. It helps to be consistent. One repeat begins with a full motif, the other with half, which can be confusing when first starting out. The plan is to begin by producing a trim or edging, an all-over pattern for significant lengths appears daunting. Dropped stitches in single bed lace are no fun, in rib they may not even be noticed until the knitting is off the machine. The difference between the two repeats: the 2 grey rows on the left are replaced by black pixels or punched holes, with a blank row placed above and below each of the black row pairs. The design is now expanded from a 40-row height to a 50-row one suitable for use in a punchcard machine This explains some of the desired knitting actions Using the method described in other posts, this was the screengrab imported into Gimp. The grey line is a reference point. Cropping the image to content will allow the last blank row to be preserved by having the grey one there. After the crop, it can be bucket filled with white, or when the image is, in turn, bitmapped to B/W, you may find it disappears. Image scale is then used to reduce the repeat for knitting. This is the repeat used to knit the swatch in my 930. If working from it, punchcard knitters need to mirror designs from an electronic source such as this and will find it easier to do so by turning the card over, marking the holes that require punching on that side, doing so, and then inserting the card in the reader in its usual orientation.  The 930 .png: Prior to knitting the pattern using the ribber, it pays to test the repeat single bed to get a sense of where the knit rows occur and to make certain the transfers are happening in the correct direction and in what place on the needle bed. There should be no side by side empty needles, and in this design, the first pairs of transfers result in 3 stitches on one needle in the center of each shape, not side by side holes as seen here in the false start prior to mirroring the image Making things work: both carriages will be operating to and from the left-hand side. The process is facilitated by the use of an extension rail and a color changer. The knit carriage alone will operate to preselect the needles that will need to be hand transferred to create the lace pattern. With the following modification of the repeat, all transfers are made moving away from the knit carriage. So if the KC is on the right, transfer to the left, if it is on the left, transfer to the right. The paired carriages will create the two all-knit rows between lace segments. The blank rows above and below the two all punched or black pixel rows are there to return the carriages to the proper, left side to begin preselection for the next row of transfers. If any end needles are preselected on the knit bed, push them back to B.
It is best to knit 2 rows of full needle rib before beginning transfer, that will ensure that stitches on both beds are formed properly. I did not, had a spot on the cast-on where the loops were not properly placed on the comb, and that is reflected in the area that looks like a stitch was dropped. Begin with a zig-zag row from left to right, knit 2 circular rows, carriages will be on the right. Knit a sealing row to the left, followed by 2 all knit rows, ending with carriages once more on the left side.
COL: remove the yarn from the Knit carriage, hold it in color changer by pushing the adjacent feeder number
separate the 2 carriages
cancel end needle selection
KC is set to slip in both directions, it will remain there for the duration of knitting the pattern, make certain all main bed needles are in the B position
KC operates alone to the right and preselects the first row of transfers
COR transfer preselected needles to the left, away from the carriage. Make certain all needles are in the B position before the next carriage pass. KC will preselect for transfers to the right as it returns to the left side.  Repeat the process until all needles are preselected for an all knit row as you knit back to the left
COL pick up the yarn, engage the ribber carriage knit 2 rows on all needles
Repeat: *COL: remove the yarn from the Knit carriage, separate the 2 carriages, operate KC alone making transfers away from the carriage until all needles are preselected as you knit to the left. 
COL pick up the yarn, engage the ribber carriage knit 2 rows on all needles** until ready to continue in every needle rib.

This method is slow, I found it oddly meditative. It offers an opportunity to review stitch formation, thus avoiding dropped stitches. Hand transferring lace preselection on the single bed as well can sometimes make a fabric achievable that is otherwise cursed by dropped stitches and fiber issues.

Revisiting large eyelet lace, hand transferred (or not)

My recent blog post on adapting lace edgings from published sources containing studio punchcard patterns led me back to reviewing a blog post from 2013, Large eyelet lace, hand transferred (or not) that included a hand technique and an automated mesh pattern.
Since then I have moved beyond mylar sheets on the 910 or using punchcards. The present swatches are knit on a 930 using img2track. The pattern images and corresponding direction of transfers, in this case, occur on the purl side, therefore lace motifs need to be reversed either in the original image processing before download, or after download by remembering to use the mirror button to reverse the image horizontally, which is an episodic forgotten detail on my part. Adjustments in the horizontal repeats as charted here may need to be made depending on the other KM models as well.
Before my using Excel and now Numbers to produce my design charts, images such as this one were created using Intwined, a software program that became quickly unsupported, buggy, and then with no updates for use on Mac. It has long since been abandoned by me.
The first revisited repeat was edited for automation on the 930 The lace carriage makes 4 passes, followed by 2 rows knit. The arrangement at the end of each transfer sequence will have pairs of double stitches moved onto the adjacent needles, leaving 2 empty needles in between them. Placement on the needle bed should be planned, and added “border” stitches can be moved away and toward the starting number of stitches to keep eyelets forming at the side edges for all-over uniformity  the result will produce 2 pairs of doubled stitches achieved by the repeated transfers with 2 empty needles between each pair where loops and floats will form. Their locations alternate as each sequence is completed Blank rows between transfer segments are there to make certain the knit rows will happen in the proper locations at the top of each transfer sequence. The first design row transfers are to the left, the transfers to the left begin on design row 8.
LCOR is ready for the first row of transfers to the left LCOL is ready to make transfers to the right after the transfers single needles are empty, with double stitches in adjacent ones, and transfers to the left are repeated once more, this is the result, with transfer needles pushed out to show doubled up stitches After all the sequence transfers are completed, there will be adjacent pairs of doubled up stitches with 2 empty needles between each pair. As the following 2 rows are knit, the first row creates loops in the empty needles, the second pass skips those needles, forming a “float”. Looking a bit closer after the knit rows as the process repeats, the first transfer and the second transfer The pairs of stitches that have been moved anchor the 2 side-by-side loops and result in the 3-strand stitch pairs, with every other remaining pair of needles empty between them.  The LC returns to the left with no needle selection Knit 2 rows, continue in pattern.
Adjusting the tension will make for a tighter knit, I decreased it by a full number halfway up the swatch below. There is one “operator error” where I attempted to correct a dropped stitch. This fabric is composed of myriad double stitch transfers in both directions and definitely a challenge to produce in any significant size. Making those transfers by hand may wind up being the solution if yarns and automation refuse to work properly. Those short “floats” at the top and bottom of the eyelets can be reduced. This adds a hand technique to every opening, whether results are worth it becomes a personal decision. After the 2 knit rows use a tool to lift the float onto the needles holding the side by side loops Before the 2 knit rows, there will be the doubled-up loops in each of those needles, and the 2 doubled-up stitches made from the transfers are added to them as transfers continue. For all those strands to knit off properly, the whole row might best be brought out to the E position before using the knit carriage. The differences between the hooked-up float version of the pattern and the let it be one are shown in areas below the lines in the bottom corners and by arrows in the close-up Much easier and quicker to knit, though quite different, is large mesh combined with tuck stitches This chart was used in 2013 as a guide for hand technique using a 2/8 wool Knitting lace sequences in a single orientation produces a mesh that is biased. It could be the start for one more chevron shape but was not the intended fabric.
The adapted repeat: the odd number of passes between each repeating segment ensures that the following selections reverse the direction of the transfers the proper orientation for use on the 930Working out the actions in a spreadsheet, border stitches outside the fabric width may be added and subtracted to keep mesh formation along both side edges.
Needles preselected for transfer to the left during transfer, needles are preselected for transfer to the right. Doubled up stitches will now be moved during transfer, needles are preselected for transfer to the left. Doubled up stitches will now be moved during transfer, needles are preselected for transfer to the right. Doubled up stitches will now be moved during transfer, no needles are preselected. Doubled up stitches will now be moved, resulting in doubled up stitches on every other needle. Pairs of knit rows follow each of these sequences. A repeat that produces a smaller mesh with the swing right to left is found in other posts and references. Below part of a published punchcard is shown,  with the resulting swatch, and in turn, compared with the large scale version of the same mesh structure knit on the same number of stitches.  A large-scale mesh in a heart design

Single bed scales made with stitch transfers

In the past, I have explored several ways to knit scale-like fabrics aka dragon teeth/scales, and a multitude of other names. My test swatches were created using racking, pattern repeats were provided for both punchcard and electronic machines. Some of the archived material:
2018/07/19/more scales and chevrons racked fabrics 4
2016/02/22/ hand knit dragon scales
2016/02/02/ vertical racking 3: automating half fisherman in pattern-2
2016/01/13/ racking 2: vertical chevrons and herringbone

With summer here and a long absence from lace knitting, I was curious about producing scaly fabrics for the single bed. Lace transfers may be used to create folding fabrics with permanent pleats, so what about 3D shapes? I began with a repeat suitable for a punchcard machine and its limitations, adjusting it in 3 different ways A variation of Card C, with 2 rows blank after each pair of transfers throughout was used in borders in some of my lace shawls including these, made in 2011.  All 3 card designs share the fact that the lace carriage (LC) makes 4 passes followed by 2 rows using the knit carriage set for normal knit to complete the eyelets with exceptions. The exceptions are in areas where there are extra blank rows, where the lace carriage will make 6 passes in order to reverse the direction of transfers. Brother lace cards usually start with punched holes on the very first row, have 2 blank rows between LC passes that complete one sequence (here each sequence is 2 rows in height), and 2 blank rows at the top of the card.  Lace markings are few and far between, errors are easy to make when punching long cards and working in designings with pixels in particular. In this case, I did not notice until I began composing the post, and after I had completed the first test swatches that the repeat on the left has an extra 4-row segment in the top half, making it 24 stitches X 54 rows as opposed to the other two at 24 X 50.
In any lace patterning if a zig-zag is wanted in parts of the design, having 3 blank rows in planned locations will reverse the direction of the transfers from those below them. Blank squares in rows containing no punched holes (or pixels) will have no transfers, so in their absence stitches in those areas will be knit, producing extra stocking stitch rows. The spacing for such knit areas on the card may be adjusted to suit. This segment of the above designs identifies the areas in both rows and columns with no punched holes (or pixels)The knit side of the fabric is the most interesting. The swatches were first photographed as they were immediately after their removal from the knitting machine. I also tried to photograph them at an angle to show the protrusions from the surface. Pattern A: A short test version using cards B, and C When using card A, the shapes alternate vertically between all mesh ones with all knit rows at the outer edge of the folds. Using Card B, all protrusions have a fixed number of knit stitch rows at the outer fold. Card C produces an all-mesh fabric that made me think of ocean waves somehow. Turned sideways, and pressed to set the folds, the resulting fabric could provide a springboard for a host of other, different ideas: A larger swatch started on waste yarn, with 2 rows of knitting at the bottom and at the top before binding off. The design is card B, with 4 rows added to each half of the design. I am still working with the constraints of a punchcard machine, and for the moment, of retaining symmetry in the width of the “scales”. The working chart, turned counterclockwise to save space Planning for 3 repeats based on 24 stitch widths the above arrangement will, in turn, need to be mirrored for the lace pattern. My sample was knit using 2/15 wool at tension 7, using needles 36 left to 35 right The actions are reviewed here once more
The knitting in progress  I cast on loosely enough, but the bind off was too tight at the top, which should always be tested on swatches before committing to a project. The resulting fabric was photographed immediately as it was removed from the machine. I tried to touch the edges only with an iron, and mine is now overheating and doing a good job of burning my wool, thus the color changes in spots With an attempt at some steaming and pressing, the folds are retained Often the question of what fine lace is and how it is made comes up. Fine lace is a fabric against which I have a personal bias. It seems to involve a lot of work for the result unless one is using a light-colored yarn with a smooth surface to show the subtle and at times hard to observe surface changes. It fares better visually when mixed with eyelets. The yarn is shared between the needle that would normally be left empty and the one with the formed stitch already on it to its right or left depending on the direction of the transfer. If the shared yarn is dropped instead of staying in the hook of the transfer needle, as the next 2 rows are knit there will be eyelets on the ground lacking them anywhere else. Card C, knit using only the fine lace setting on the LC, looks very different from the previous fabrics, both knit and purl sides are shown, with a couple of spots where the yarn was not shared by 2 adjacent needles, forming eyeletsNow evaluating the possibility of mimicking my hand-knit versionPlanning out a repeat in chart form: Knitting began with working in a 2/15 wool, tension 6, using a 7 prong tool with all prongs engaged to transfer groups of stitches onto their new positions on the needle bed. The first two images review picking up from the row below to fill in needles emptied by transfers. It is one of the machine-knit equivalents for the M1 direction in hand-knitting patterns. As a result, the number of stitches being knit remains constant throughout the piece. The stitch structure so far appeared too loose to me, so I then switched to a 2/8 wool, at tension 7 with the intent to test knitting as tightly as possible while still facilitating the multiple moves of stitch groups on each row. The resulting fabric was stiff and wanted to curl strongly to the purl side, needed pins to help it lie flatter. The shapes refused to stay poked out to the knit side.
I seldom wash my swatches, viewing them simply as proof of concept of technique concepts, not usually as springboards for finished pieces. Generally, I stop at steaming or ironing if needed.
When I made garments for sale in wool I usually tested the swatches and washed the finished garments as well. The “hand” and the behavior of the finished piece can change considerably. The hand-washed sample in the second illustration below lies flat and has a soft, drapey feel absent in the unwashed, and retains the flatter shape with no encouragement needed. In its 2/15 portion, the “scales” also became more flattened.
Washing wool removes any sizing and excess dye. Open spaces in the knitting become reduced in fulling, as opposed to closing tightly in felting. Using a constant temperature in both the wash and rinse and avoiding excessive friction, in turn, avoids excess shrinkage. On electronic machines, one does not have the same limitations in terms of the width of the repeat maxing out at 24. For example, the number of eyelets on either side of the block components of the repeats may differ, the greater the number of eyelets, the wider the spacing between the 3D shapes. Graduations may be planned in height and width of repeat blocks across the full needle bed, limited only by patience in designing, the capacity to download, and the tolerance for both the yarn and the operator to complete wide, long pieces using the technique.

Experimentation can yield quick results, sometimes with unexpected but pleasant surprises. One of my best-selling felted items for a couple of decades was an accessory that was planned deliberately to mimic a test piece that had almost been tossed in the trash. It’s good to return to things after a break for another look, and then it is really helpful if notes were kept. Another variation of the A-C cards in single repeat was tested at the bottom of the swatch below and in a staggered one, tested at the top of the swatch The “scales” were more like twisty bumps, with subtle variations vertically in some of the stitch groups. That said the results were dramatically different when color changes were added to the pattern knitting in the shorter repeat. Blocking may make an even more marked difference depending on whether the mesh (lightly steamed) or the tighter knit (vertically pulled, should be washed) produces the preferred effect. The looser stitches at the top outside edge ie at the top left corner are the result of a stitch that got away from me. The cast on was a bit too loose, I knit 4 rows at the bottom after the cast on and 4 rows at the top of the repeat before binding off. The differences in the width of the same fabric are dramatic. Any overall mesh/ lace fabric blocked for openness such as on the left will grow in length over time, is best stored flat, and will benefit from episodic pressing/ steaming to reset the width. Then I began counting eyelets, which were equal in number in the schematic for the repeat, but not equal in number on either side of the center pivot for the bend in the herringbone shape when the piece was finished. Any extra eyelet rows in the same direction will result in increased biasing in those sections.
Time to test more mesh variations, a topic for another day.

Machine knit leaves using slip stitch with holding

In 2012 I had a sort of leaf obsession, which led to my exploring a range of shapes created in both hand and machine knitting, including a series of shawls that were machine knit, using the lace carriage, intended for both gifts and sale.
Online resources were not as abundant back then, searches are more productive now via browser searches, pinboards, and Ravelry.
I have always been interested in holding techniques and automating them on both punchcard and electronic machines. In recently revisiting shell shapes I was reminded of leaves once more and thought I would return to working with them.
An early abandoned effort in trying to construct leaf shapes automating their shaping using holding in combination with slip stitch followed other earlier posts is shown below. In all honesty, I have been blogging long enough so I often do not recall previous writings on a recent spark of interest and execute a personal version of reinventing the wheel, starting from scratch, or executed poor note-keeping which in turn requires it.
A variety of lozenge and “leaf”-shaped forms may be found in previous posts on holding intarsia, some are strictly hand-selected, others are automated. There is a series of 5:

Checking the repeat for a single shape Adding a second color and reversing directions of shapes brings lots of yarn ends and its “price to pay”Some handknit large scale inspiration to begin my revisit to MKing them: Garnstudio 1 and Garnstudio 2, which introduces lace transfer stripes between leaf forms  A free hand knitting pattern, “Papagena“, that takes similar shapes to a triangular layout for shawl shaping Stitch Maps is an online source for hand knitters with interesting graphics that include some for held shapes, such as this The chart is actually rotated 90 degrees counterclockwise, could serve as inspiration for an electronic pattern.

Returning to a possible far smaller repeat that may be executable on a  punchcard machine as well. The central vein in the forms is created by having held stitches with no wraps along and up to its center in height, creating 2 continuous shapes that mirror horizontally and repeatAutomated holding sequences may be planned for single or multiple stitches in width, as well as for single and multiple rows in height. For the new initial test, which proved to need editing, this was my repeatA tiny test in too thin a yarn I am knitting on a 930, the image needs to be mirrored in order for it to appear in the direction I intend on the knit side. The above repeat did not work properly when knitting a whole row of shapes. With some patience, a final, edited, and mirrored repeat was developed that enabled a completed a full row of shapes using the slip setting and holding, and starting with working it from right to left. Sometimes differences are subtle, especially in designing using single-pixel units. The new repeat proved to also work for rows of shapes in the reverse direction after horizontal mirroring and restarting the pattern or design row 1. When working from right to left, the initial preselection row is from left to right, while when working from left to right, the first preselection row is from right to left. After a full row of repeats is completed, the pattern is rolled back to row 1 and mirrored. Punchcard knitters could turn the card over and start again on the proper row. I used contrast color knit rows initially in between rows of shapes to help me note transitions more clearly. The “leaf” is not pointy enough for me, but at times what was not planned may lead to a pleasing result of a different sort.
The amended, corrected repeat is shown on the right To knit: cast on with a multiple of 12 stitches on each side of the center 24 on the needle bed
Cancel end needle selection
COL: first preselection row from left to right
COR: set machine for both slip <– –> and hold
all needles will have been preselected, knitting every stitch, knit 2 rows, return to the right, as the row is knit, patterned preselection occurs
COR: bring all needles to the left of the first 12 on the right into hold position, knit until all needles in the group of 12 are preselected again, the carriage will be on the right
*COR: bring a group of 6 needles to the left of the 12 stitch group just completed into work, knit one row to left
COL: bring 6 stitches from the completed shape on the right to hold, continue in the pattern on the new  12 stitch group until all 12 stitches are once again preselected, stopping with COR***
repeat * to *** end working the full last group of 12 stitches on the left, including the last 12 stitch preselection

At the completion of a row of shapes COL: make a decision about the transition, whether any extra rows knit are a problem or not, and whether added rows in contrasting colors are wanted. To proceed with no changes in cam settings and 4 rows of knitting between the rows of shapes remembering that the first preselection row needs to be made from right to left.
COL: manually return all needles to upper work position (D). They will knit row 1 of the stripe
COR: manually push all needles to D again, return program to design row one, check settings, as the first design row pattern is preselected an all knit row 2 will be added. As patterning resumes from the left another 2 all knit rows will be produced before selective patterning occurs.
If any extra all knit rows are wanted cancel patterning on the knit carriage, set it to N, knit the extra rows, remember to end on the proper side for the first preselection row, and what options may be necessary to complete that row correctly.
To reverse patterns without extra knit rows:
COL: store yarn.  The carriage can be removed and brought to the opposite side, or stitches need to be manually be placed in the B position for a free pass to the right. This involves placing the cam selector button on N, returning the cams set to slip in both directions.
COR, all needles also need to be in work in B position, no yarn, in order to make a free pass to preselect from right to left, ending COL
COL: pick up yarn and continue in pattern. These textures require a lot of carriage passes, which tend to fuzz up the yarn on the purl side of the knit a bit. The shape I created was not very leafy to my mind, but still interesting, especially on the purl side. The yarn used in a 2/15 wool, knit on Tension 5Moving on to a wider version, using 24 stitches in width to allow for using the pattern on a punchcard: this repeats works both as-is and mirrored, the groups of stitches moved in and out of work is now half of the new design repeat = 12. Making the repeat work in any number for this shape involves lining up the needle selection in each group of needles and constant counts for holding sequences. Punchard knitters would need 2 separate cards. The lovely mess in the swatch happened when I stopped paying attention to everything but what was happening on the needle bed and missed the tangle of yarns in my yarn mast. There is enough knitting, however,  to note that the repeat is sound and that the edges on both sides are formed by the narrowest part of the shapes in each direction. One way to solve that is by casting on and binding off along tops and bottoms of shapes as seen in the yellow and green swatch at the top of the post. Planning things out to release those edges as seen at the top of the post

Working on outlining the shapes with contrast color: Problems to solve: maintaining an even number of rows in-between shapes and a straight edge along both sides. The latter could happen with triangles prior to knitting full shapes at either or both ends, the first sample failed on the left side due to both triangles being knit in the same sequence;   that may be solved by beginning shaping on 2 stitches on the left rather than the full 12, mirrored. The proper sequence for actual knit stitches for the first, bottom set, and mirrored for the second, top set still only partway there I am presently knitting with my left hand in a splint that has exposed velcro teeth, which has caused some interesting issues with actual knitting and with yarn snags. To end this latest effort, in yet another knitting aaargh! moment, it appears my iron is now overheating and burned the wool! From observing the above swatch on the purl side it looks as though each row of shapes needs to have a triangular shape at each end. Also, the contrasting color line thickness is not constant. The purpose of automation should be to make things easier, not confounding. After yet another trial, I decided to give up on attempting to use the automated repeat to produce an effect that was consistent and made me happy.

Setup for a leaf in each color is far less fiddly and simpler to execute. A tentative layout and knitting sequence:
Begin on waste yarn, decide on the color of the cast on, and any additional knit rows prior to beginning in the pattern. Each of the side triangles is shaped using manual holding techniques over 12 stitches. If starting on the right, the first preselection row needs to be made moving from left to right as above on the first 24 stitches. With knit carriage set to both slip in both directions and holding with COL make certain the first 24 stitches on the right in B position make a free pass to the right.
COR: cut yarn, change color, knit the first shape repeat, end COR
COR: when all needles in the group are preselected, push the first 12 needles on the carriage side out to holding position, push 12 stitches on their left back into upper work position as you would in any holding pattern, they will knit in the slip setting as well. Cut the yarn, change color, repeat across the row of shapes
COR: when the last group of 12 needles on the left is preselected with all needles out to hold or removing the carriage and positioning it on the other side, begin knitting COL.
COL: manually knit triangle at top of the previous row of shapes
If a contrasting color stripe or any other pattern is intended between a full row of shapes, execute them and end COL
COL: shape the second triangle for the start of the reversed row of shapes, get the carriage to the right side by a pass over all needles in holding position or removing the carriage and bringing it to the opposite side
COR: the second pattern is programmed. Punchcard knitters use the second card, electronics mirror the shape. With the first 24 stitches on the left in B position and the knit carriage set for holding and to slip in both directions, make a preselection pass to left.
COL: change color, knit shape, and continue on as described above reversing shaping
As with intarsia, there will be lots of yarn ends to weave in and clean up those eyelets at the start of each color change. The swatch after a quick pressing

The possibilities could be endless.  Electronic machines do not have the limitation of working within the 24 stitches maximum design width. Shapes can be fully automated using only slip stitch setting, no holding, but repeats become exponentially wide and long. The technique merits its own post.

 

 

 

 

A hand knit consult to machine knit slip stitch

I was contacted via a comment here about the possible methods for reproducing this handknit pattern Observations: there are elongated loops on the knit side of the fabric, likely created with slipped stitches. There appear to be eyelets on the purl side. The total number of stitches remains constant throughout the knit. The row repeat spacing is fairly close, so at least to start with I tried single repeats to achieve the look, was not pleased with any of the initial results. That led me to an online search for what would visually appear to have similar qualities in handknit samples.  Knittingfool.com is an extensive resource and, to my eye, this slip stitch pattern, “little birds”,  shares similarities with the above swatch as do “oats” found in a 1984 handknitting publication  I have a hard time with longhand written instructions for patterns nowadays, have grown so used to creating or working from published charts. As usual, I plan out tentative repeats and ideas, began with this,  toying with where to place slipped stitches and then transitioned to translating any repeats for use in machine knitting, keeping in mind that in hand knitting actions are made as the row is being knit, while in machine knitting they take place prior to returning the carriage to the opposite side thus knitting that row. This was my first repeat after replacing cells with squares representing knit stitches with black and white planned pixels for electronic download.
On the machine, the distance between stitches is fixed, so for any crossings or lots of movement across the needle bed it is best to use yarn with a bit of stretch, and a stitch size large enough to allow for the desired actions. I found slipping for 2 rows only did not create enough loop length, so I changed the slip stitch areas to 3 rows in height. The slip stitch setting is used in both directions throughout. White squares represent areas where needles on the bed are skipped/slipped, not being selected forward and thus knit. This happens for 3 rows, resulting in the required elongated stitches. On the 4th pattern row, the group of 3 not selected needles is where the stitch transfers and crossings occur. Any cabling, eyelet fill-in, etc, needs to be performed prior to knitting that row and moving the carriage to the opposite side. The work is always done with purl side facing, so matching the direction of patterning to a hand-knit may also require mirroring of crossings, depending on your knitting machine model. The goal is to have the K3tog with the long loops in front of the single knit stitch in the center position.

To execute the slip stitch crossings in front of the center knit stitch on the knit side of the fabric transfer the center stitch in the group of 3 and hold aside, take the left elongated stitch and move it onto the now empty needle at the center position of the group of 3transfer the elongated stitch on the right onto that same center stitch. This may be done in the reverse order to have loops move in the opposite direction on the knit side of the fabric. Move the stored original center stitch back onto that center position, there will now be 3 stitch loops held on the single needle fill in the empty needles to avoid large eyelets, picking up from the row below repeat the process across the bed, bring all the needles used out to hold position prior to knitting the next row The yarn used was 3/8 wool at loosest tension possible, the result is subtle as any spaces between stitches get pretty well filled in. Moving on to denser patterning The elongated stitch crossings now happen every 4 rows, but across two needles, not one. I used a tightly twisted rayon for the test swatch thinking they might be more visible, but the openness in the stitch formation because of the fixed spacing on the metal bed confuses the texture a bit. Simply leaving the empty needle out of work and continuing to knit (1) created too large an eyelet to my taste. Trying to pick up the third slipped loop (2) had the same effect. The best result was obtained by picking up from the row below on each side of the three stitches that are removed and then returned to the needle bed (3).
When pattern row 4 is reached, the not selected stitches are removed on a 3 prong tool, the elongated stitches are moved onto the center needle of the now resulting group of 5e wrapping the third row of floats can be tested by inserting a single eye tool front to back, twisting either counter or clockwise and rehanging on an empty needle, thus casting on an “extra” stitch going back to picking up from row below this shows the number of skip stitch floats in each test the appearance on the knit side comparison to the handknit. Charting the actions for a hand-knit version: the top images illustrate the moves on the purl side while on the machine, below it those on the knit side when hand knitting the patternPlotting out borders and repeats for a small test including make-1 increases in order to keep the total stitch count constant. I do little hand knitting nowadays, so when doing so I add as much information as possible including some stitch counts until the pattern is established and I can visually follow it more easily. The resulting test swatch Comparison with the original: I knit 3 together through front loops, so my long stitches are crossed in the opposite direction of the original. Knitting through the back of the 3 stitches would reverse it and yield a matching result. This is an  illustration of the method I used to “make one”,  in my swatch I kept the direction constant
